OIL PRESS.

suitable cloths being interposed as found desirable. rIhe band is thenplaced in the box A with its top mat-plate resting against thedrainage-plate E and its bottom mat-plate resting on the iianges of theband H. The platen or division-plate of the box A below should come upagainst the bottom of the band H, and hold the latter from droppingdown. Vhen pressure is applied to the machine in the usual manner, theoil-meal is pressed between the top and bottom mat-plates l, causing theoil to be extracted therefrom, said oil being forced out in twodirections-viz., up through the openings u of the top-plate I into theslots m of the drainage-plate E, from whence it is carried by thefilling o to each side of the box and out through the passages n to thebox below, and, second, down through the openings u of the bottommat-plate I to the platen or divisionplateD of the box A below.

It will be observed that the transverse sha1- low grooves 7c registerwith the openings u of the bottom matplate, so that the oil will dropinto the said grooves k, traverse the same until they cross the iirstlongitudinal groovej,enter the latter and pass along, and through theslots Z of the platen D into the grooves g f/ and pockets h on the underside thereof. The oil asl it accumulates in said grooves and pook. etsis allowed to work out through the front and rear ends of the plateninto the gutter or trough c, from whence it is carried off in the mannerbefore explained. Vhen the oil has been extracted, the pressure isrelieved and the various bands containing the dry oil cake removed inthe manner explained.

It will be observed that the peculiar construction of the slots m of thedrainage-plate E serves to hold the wool or other filling firmly thereinand prevent it from working out of place. It will also be seen that bymeans of the detachable side plates, F, the latter may be removed towithdraw the drainageplate E for cleaning the same, as desired.

Our improvements are simple 4in construetion, efficient in operation,and will prove of great utility for the purposes intended.

Having described our invention, we claim 1. In an oil-press, thecombination, with the telescopic boxes, of d rainage-plates attached tothe same and provided with grooves or channels having hair, wool, orother filling to form conducts for the oil and hold the same fromreturning to the cake when pressure is relieved, as and for the purposeset forth.

2. In an"V oil press, the herein described drainageplate,having hair,wool, orequivalent lining fitted in grooves or channels thereof to formconducts for the oil, as and for the purpose set forth.

3. In an oil-press, the combination, with the telescopic boxes, of thedrain-plate resting against the under side ofthe box, and the sideplates or walls attached to the box for holding the drain-plate inposition, but allowing its detachment at will, for the purpose setforth.

4. In an oil-press, the combination, with the telescopic boxes, of thedrain-plate and the side plates or walls for holding the plate inposition, the top edge of the side plates or walls being cutout to allowthe oil to escape from the drain-plate back or in rear of the sidewalls, for the purpose set forth.

5. In an oil-press, the combination, with the teleseopicboxcs havingdepending walls, ofthe drain-plate fitted between the walls, and theside plates secured to the depending walls and holding the drain-platein position, for the purpose set forth.

6. In an oil-press, the combination', with the telescopic boxes havingdepending walls which are liuted or cnt out on their inner faces to formpassages, of the drain-plate fitted between the walls, and the sideplates secured to the said walls and holding the drainplate in position,the top edge of the side plates being cut out to allow the passage ofthe oil from the drain-plate, over the same, and through the passagesformed in the depending walls, as and for the purpose set forth.

7. In an oil-press, the combination, with the telescopic boxes having aseries of steam channels provided in the same, of t-he steam-inletcommunicating with the first of the series and the steam-outlet with thelast of the series, whereby the steam delivered by the inlet will have acontinuous circulation through all of the steam-channels and be finallydischarged through the outlet, as and for the purpose set forth.

8. In an oil-press, the combination, with the telescopic boxes havingaseries oi steam-channels provided in the same, the first channelshaving communication with the second at one end and the second with thethird at the opposite end, and so on alternately through the entireseries, of the steam-inlet connecting with the first channel and thesteam outlet with the last, as and for the purpose set forth.

9. In an oil-press, the combination,with the telescopic boxes havinggrooves or channels provided in the upper face thereof, which grooves orchannels have free communication with each other at the ends, of a steaminlet and outlet and a division plate or platen secured over the boxesto form a tight cover for the steam channels or grooves, for the purposeset forth. l

10. In an oil-press, the combination,with the telescopic boxes, of thedivision plate or platen having deep grooves eut longitudinally thereofand shallow grooves running transversely and crossing the deep grooves,for the purpose set forth.

11. In an oil press,the combinatiomwith the telescopic boxes, of thedivision plate or platen having deep grooves cut longitudinally in itstop face and shallow grooves running transversely and crossing the deepgrooves, channels provided in the under sideof the platen, and slots cutthrough the longitudinal deep grooves, so as to allow communication withthe grooves in the under side, for the purpose set forth.

12. In an oi1-press,the combination, with the telescopic boxes, of thedivision plate or platen having grooves orv channels cut in the underside thereof, grooves provided in the top face of the platen, and slotsout through the top grooves, so as to allow communication with thegrooves or channels in the under side, for the purpose set forth.

13. In an oil-press,the combination,with the telescopic boxes, of thearm oroam working through a slot or opening of the saine to remove themat or band therefrom, for the purpose set forth.

14. In an oil-press, the combination, with the telescopio boxes, of thearm o'r cam, the rockshaft on which it is mounted, the connectingbar,and the operatinglever, arranged and operating for the purpose setforth.

15. In an oil-press, the combination,with the telescopic boxes, of theband for holding the meal in place while undergoing pressure, oomprisinga rectangular frame made solid at the corners, for the purpose setforth.

16. In an oil-press,the oombination,with the telescopio boxes, of theband for holding the meal, comprising a rectangular frame open at thetop and bottom, flanges provided' at the bottom, and a mat-platesupported on the flanges, for the purpose set forth.

17. In an oil-press,the combination,witl1 the vthe drainageplate havingits grooves or channels filled with hair or wool, the supplemental sidewalls or plates to hold the drainage-plate in position and also allowthe oil to flow in rear of the side walls, the steam-channels providedin the top face of the boxes, the platen serving as a cover for thesteam-channels and grooved to allow the flow of oil, theband for holdingthe meal, and the mat-plates working in the band, for the purpose setforth.
